The Nevada Democratic Convention on May 14 met with chaos as Bernie Sanders supporters protested the results and process of delegate allocations. Reports of protesters throwing chairs and death threats made to to Nevada Democratic Party chairwoman Roberta Lange have been making the rounds.

With the recent events, members of the Democratic party worry that the chaos will repeat itself at other state conventions and at the national convention in Philadelphia this summer.

“You’ll see similar things happen in other state conventions elsewhere in the next few weeks. I don’t know if it will be to the same extent as Nevada,” predicted Ken Martin, chairman of the Minnesota Democratic-Farmer-Labor Party.

“I can’t imagine that tensions will be this high come late July [at the national convention]. But obviously if they are, that would be a problem.”

At the Nevada Convention, tension ran high when Sanders supporters accused state party leaders of putting them at a disadvantage, objecting to procedural votes to approve the rules of the event.

State party officials said the would-be delegates didn’t provide acceptable identification and did not meet the May 1 deadline to register as Democrats.

The Democratic party, which has sought to portray themselves as the party of unity against a divided Republican party, has had a tough time getting supporters of Sanders behind frontrunner Hillary Clinton.

“We will be reaching out to the leadership of both of our campaigns to ask them to stand with the Democratic Party in denouncing and taking steps to prevent the type of behavior on display over the weekend in Las Vegas.”

Democratic Minority Leader, Senator Harry Reid from Nevada said that he let Sanders know everything that happened at the convention, and called it a “test of leadership”:

“I wanted to make sure he understands, that he’s heard what went on there. The violence and all the other bad things that has happened there,” Reid told reporters.

“He said that he condemns that. And I’m confident that he does. I’m confident he will be saying something about it soon. This is a test of leadership, as we all know, and I’m hopeful and very confident that Sen. Sanders will do the right thing.”

Sanders Condemns Violence and Nevada’s Democratic Party

Sanders condemned the violence, but took aim at the DNC’s claim that the Sanders supporters had a “penchant for violence” in a statement:

“That is nonsense. Our campaign has held giant rallies all across this country, including in high-crime areas, and there have been zero reports of violence. Our campaign of course believes in non-violent change and it goes without saying that I condemn any and all forms of violence, including the personal harassment of individuals,” Sanders said.

He then listed grievances concerning the procedures at the convention and against the Nevada Democratic Party:

“The chair of the convention announced that the convention rules passed on voice vote, when the vote was a clear no-vote. At the very least, the Chair should have allowed for a headcount,” Sanders continued.

“The chair allowed its Credentials Committee to en mass rule that 64 delegates were ineligible without offering an opportunity for 58 of them to be heard. That decision enabled the Clinton campaign to end up with a 30-vote majority. The chair refused to acknowledge any motions made from the floor or allow votes on them. The chair refused to accept any petitions for amendments to the rules that were properly submitted.”
